         2 . The space heating system according to  claim 1 , wherein
 all of the plurality of heat source controllers are configured to increase the setting values based on the heating request transmitted to the predetermined heat source controller.   
     
     
         3 . The space heating system according to  claim 1 , further comprising a condition determinator configured to determine whether a predetermined condition based on the heating request is satisfied,
 wherein in response to the condition determinator determining that the predetermined condition is satisfied, the heat source controller that is not the predetermined heat source controller increases the setting value.   
     
     
         4 . The space heating system according to  claim 3 , wherein
 the plurality of heat source controllers includes one parent controller and at least one child controller communicable with the parent controller, and   the parent controller functions as the condition determinator.   
     
     
         5 . The space heating system according to  claim 3 , wherein
 the predetermined condition includes a first predetermined condition that the heating stop request has not been generated for more than a first predetermined period since the heating start request was generated.   
     
     
         6 . The space heating system according to  claim 3 , wherein
 the predetermined condition includes a second predetermined condition that at least one of the plurality of heat source devices keeps performing the first heating operation for more than a second predetermined period after the heating start request was generated without the heating stop request being generated.   
     
     
         7 . The space heating system according to  claim 1 , further comprising a hot-water supply circuit in which water flows,
 wherein each of the plurality of heat source devices is further configured to perform a second heating operation for heating the water flowing in the hot-water supply circuit, and   each of the plurality of heat source devices is unable to perform the first heating operation while the heat source device is performing the second heating operation.   
     
     
         8 . The space heating system according to  claim 2 , further comprising a condition determinator configured to determine whether a predetermined condition based on the heating request is satisfied,
 wherein in response to the condition determinator determining that the predetermined condition is satisfied, all of the plurality of heat source controllers increase the setting values,   the plurality of heat source controllers includes one parent controller and at least one child controller communicable with the parent controller,   the parent controller functions as the condition determinator,   the predetermined condition includes a first predetermined condition that the heating stop request has not been generated for more than a first predetermined period since the heating start request was generated,   the predetermined condition includes a second predetermined condition that at least one of the plurality of heat source devices keeps performing the first heating operation for more than a second predetermined period after the heating start request was generated without the heating stop request being generated,   the space heating system further comprises a hot-water supply circuit in which water flows,   each of the plurality of heat source devices is further configured to perform a second heating operation for heating the water flowing in the hot-water supply circuit, and   each of the plurality of heat source devices is unable to perform the first heating operation while the heat source device is performing the second heating operation.
